Km's per tank for 5.7Gen3 V8?

[bennzy]

i got a bit over 520km out of a gas tank that was highway driving and a little bit of town driving while booting my gassed gen3 was pretty happy with that, will get better kays if the road wasnt windey and was mainly one speed.

normal work driving i get about 300 or more out of a tank including booting.

VY SS Auto, bout 16.3/100kms. City driving pretty much all the time, Not sure how much it gets to a tank exactly because we dont let it get down to a quarter of a tank anymore (fuel gauge problems).
